Hydroxamate for Copper Oxide Flotation

2013-7-25  The various copper occurrences in an ore are referred to in the industry as “Acid Soluble”, “Oxide Copper” or “Non-sulfide” copper on the basis of chemical analysis, thereby leaving no room for the possibility that much of this “Acid soluble” copper may not be present as well defined oxide minerals and that they may not even be amenable for flotation either with oxide collectors or with sulfidization-xanthate flotation.
